"Evolution of parton distribution functions in the short-distance factorization scheme"

Presented by Dr. Herve Dutrieux, William & Mary College

Friday, October 27, 2023, 11:00 am — Large Seminar Room, Bldg. 510

Abstract: Lattice QCD offers the possibility of computing parton distributions from first principles, although not in the usual MSbar factorization scheme. I will present the evolution of non-singlet parton distribution functions (PDFs) in the short-distance factorization scheme which notably arises in lattice calculations in the pseudo-distribution approach. I will provide an assessment of non-perturbative evolution of PDFs from already published lattice matrix elements and show how this evolution can be used to reduce the fluctuation of the lattice data. By highlighting the limitations of the current computations, I will advocate for the possibility to use lattice calculations in small volumes.
